DoublePlay never worked smoothly forever until this last update on Genie. This is a highly used feature for me. I pause one channel and switch to another, then pause it as well so I can watch 2 channels for commercial skipping. If you were in DP mode and wanted to switch using the "down" button it would kick you back to the same channel you were on. You'd have to press the button numerous times to get it to work. I think it had something to do with changing resolution from a 1080 to 720 (or vice-versa) source. But now it appears they finally have fixed it after these many years of frustration.
